on my 928 with an 8pin CDI,
I had Opto+ connected to the tachometer output of the Porsche CDI ignition controller and Opto- simply grounded
as far as I'm aware the VR+ and VR- have been left disconnected on most if not all installs (including my v2.0) with no ill effects

I can't see any reference in the current microsquirt manual on the mentioned setup modification to VR for OPTO input

VR+ to tacho and VR- disconnected, instead of the OPTO was an option mentioned back in post 617

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS
